which is by linear regression analysis. Regression analysis includes any techniques for modeling and analyzing several variables‚ when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically‚ regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied‚ while the other independent variables are held fixed. Most commonly‚ regression analysis estimates

Regression Returns in Financial Modelling It is preferable not to work directly with asset prices‚ so we usually convert the raw prices into a series of returns. There are two ways to do this: Simple returns or log returns Regression is probably the single most important tool What is regression analysis?

1. In Chapter 5‚ of Supercrunchers‚ "Experts versus Equations"‚ the author makes a great case for the fact that equations predict better than humans. What reasons does the author give that illustrate why a human cannot make predictions as well as an equation? Reason 1: the human mind tends to suffer from a number of well documented cognitive failings and biases that distort our ability to predict accurately. Reason 2: Once we form a mistaken belief about something‚ we tend to cling to it. We are

Introduction Exchange rates play a vital role in a county’s level of trade‚ which is critical to every free market economies in the world. Besides‚ exchange rates are source of profit in forex market. For this reasons they are among the most watched‚ analyzed and governmentally manipulated economic measures. Therefore‚ it would be interesting to explore the factors of exchange rate volatility. This paper examines possible relationship between EUR/AMD and GBP/AMD exchange rates. For analyzing relationship
